Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

This book was released on 2021 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single stock terminal fisheries for Fraser River sockeye salmon (Oncorhynchus nerka) have been proposed as an alternative to lower-river mixed-stock fisheries to avoid weak stocks and support terminal allocation objectives. However, increasing natural mortality rates during the upriver migration (en route mortality) have been overlooked when evaluating alternative harvest strategies. I used a spatially explicit, individual based model of sockeye migration and fisheries to examine how fishery location options affect management performance under variable en route mortality scenarios and a fixed total catch objective. Under all scenarios tested, re-distributing a fixed total harvest from lower-river mixed-stock to multiple upper-river single stock terminal fisheries resulted in increased en route mortality, decreased spawner abundance, and, in most cases, reduced total catch. While lower-river mixed-stock fisheries performed better at meeting a fixed catch objective under the scenarios in my analysis, single stock terminal fisheries may be preferable for meeting other objectives.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is often recognized that a quantitative assessment of the cumulative effects, both additive and non-additive, of multiple stressors would provide a more realistic representation of the factors that influence sockeye salmon (orhynchus nerka) migration mortality. Towards achieving this type of assessment, this research project first presents a literature review of multivariable methods currently applied in Fraser River sockeye salmon migration studies and in the fields of fisheries, biology, and medicine which could be used to analyze cumulative effects. Papers taken solely from Fraser River sockeye salmon research revealed a limited number of multivariable methods being applied and the sub-optimal reliance on univariable methods for multivariable problems. The review of fisheries and biological science literature identified a number of additional methods for dealing with cumulative effects while the review of medical science literature did not reveal any additional methods. The literature review also presents a guide for how to apply each of these methods to other cumulative effects studies and more specifically how to apply them to study Fraser River sockeye salmon migration survival. The second part of this project presents an application of two of these multivariable methods, regression trees and random forests, to describe and predict the cumulative effects of multiple habitat and stressor variables on Fraser River sockeye salmon prespawn mortality (PSM). The results of this analysis show that although a number of these variables may relate to sockeye salmon PSM, only a few variables representing the timing of entry into the Fraser River, the destination spawning ground, and human population density are required to predict Fraser River sockeye PSM.
